Abstract
The utility model relates to a two grades of gear automatic transmission of semi -axis formula, it includes output shaft, first gear, shift fork, first ring gear, input shaft, jackshaft, second ring gear and second gear, wherein, first gear, shift fork and second ring gear bonded are on the output shaft to output shaft axial displacement can follow, first gear ability and the meshing of first ring gear, the shift fork can promote first gear and second ring gear, first ring gear pin joint is on the output shaft, set firmly on the input shaft the second gear, the jackshaft meshes with input shaft, first ring gear respectively, second ring gear ability and the 2nd gear engagement. The utility model discloses an it is nimble that two grades of gear automatic transmission of semi -axis formula has an adjustment of compact structure, drive ratio, and input/output a great deal of advantage such as various informative.
Description
[technical field]
The utility model relates to a kind of speed-changing gear box, is specifically related to a kind of semi-shaft type two grades of gear automatic gear-box, and it, in gantry within 3000rpm of rotating speed and heavy high pulling torque horizontal boring and milling machine, belongs to technical field of lathe equipment.
[background technology]
At present, the heavy plane milling and boring machine General Requirements of China takes into account certain high speed performance, and requires to possess low-speed big characteristic, and corresponding gearbox has manually and automatic two large classes.Automatic gear-box adopts again German ZF, Italian BF planetary reduction gear and self-control straight-tooth slip fork type gearbox usually.ZF and BF planetary reduction gear precision is high, of many uses, is particularly suitable for the stock-removing machine within 1400Nm, when for heavy or more high pulling torque lathe time, often standard specification price is high, and size is large, installs limited.And straight-tooth shift fork gearbox is relatively little with weight/HP ratio, and straight-tooth rotating speed is limited, and noise is larger.
And domestic conventional self-control reduction box arrives two-stage straight-tooth power shift gear for what helical gear adds one, size is corresponding also larger.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of Novel half-shaft formula two grades of gear automatic gear-box, to overcome described defect of the prior art.
[utility model content]
For solving the problem, it is flexible that the purpose of this utility model is to provide a kind of compact conformation, gear ratio adjustment, and semi-shaft type two grades of gear automatic gear-box that input/output format is various.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of semi-shaft type two grades of gear automatic gear-box, and it comprises output shaft, the first gear, shift fork, the first gear ring, power shaft, jackshaft, the second gear ring and the second gear; Wherein, described first gear, shift fork and the second gear ring are bonded on output shaft, and can move axially along output shaft; Described first gear energy and the engagement of the first gear ring; Described shift fork can promote described first gear and the second gear ring; Described first gear ring is articulated on output shaft; Described power shaft is installed with described second gear; Described jackshaft engages with power shaft, the first gear ring respectively; Described second gear ring energy and the second gears meshing.
Semi-shaft type of the present utility model two grades of gear automatic gear-box are set to further: described output shaft and power shaft are oppositely arranged.
Compared with prior art, the utility model has following beneficial effect:
1. compact conformation, only uses two group axle system holes can realize 2 grades of adjustment;
2. gearratio adjusts flexibly, and low speed group gear can be easy to adjustment as required, ensures that number of teeth summation is constant, or carries out gear modification, easy to adjust;
3. reduction box sideshake is little, and when direct connection, gear ring Coupling Clearance is reduction box gap, only ensures that two groups of gear clearances can control sideshake, easily realize accurate pointing during low or first gear;
4. parts are less, and cost is low, and running is reliable, extensively can be suitable for the occasion milling axles such as gantry, horizontal boring and milling machine and general milling machine and match.
[accompanying drawing explanation]
Fig. 1 is the sectional view of semi-shaft type of the present utility model two grades of gear automatic gear-box.
[detailed description of the invention]
Refer to shown in Figure of description 1, the utility model is a kind of semi-shaft type two grades of gear automatic gear-box, and it is assembled by a few parts such as output shaft 1, first gear 2, shift fork 3, first gear ring 4, power shaft 5, jackshaft 6, second gear ring 7 and the second gears 8.
Wherein, described first gear 2, shift fork 3 and the second gear ring 7 are bonded on output shaft 1, and can move axially along output shaft 1.Described first gear 2 energy and the first gear ring 4 engage.Described shift fork 3 can promote described first gear 2 and the second gear ring 7.Described second gear ring 7 energy and the second gear 8 engage.
Described first gear ring 4 is articulated on output shaft 1.
Described power shaft 5 is installed with described second gear 8, this power shaft 5 and output shaft 1 are oppositely arranged.
Described jackshaft 6 engages with power shaft 1, first gear ring 4 respectively.
The operation principle of semi-shaft type of the present utility model two grades of gear automatic gear-box is as follows: motor directly to be connected with power shaft 5 by shaft coupling or belt is connected, when shift fork 3 drives the second gear 8 to enter the second gear ring 7, directly and motor direct connection, now gearratio is 1:1 to output shaft 1, is top gear; When shift fork 3 drives the first gear 2 to enter the second gear ring 7, output shaft 1 is separated with power shaft 5, and power shaft 5 is delivered to output shaft 1 again through jackshaft 6, slows down through two-stage helical gear, gearratio is 1:4 (can adjust the number of teeth as required), is low or first gear.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
